Silk, of which the following is a specification.

My invention relates to artificial silk spinmounting of the spinning nozzle and associated'parts. The object of my invention is to provide an. improved assembly of the nozzle arm, filter and'pump with relation to the driving apparatus, and for protecting the latter against fouling, as Well as. for catching and preserving waste solution.

The accompanying drawing shows the apparatus in side elevation with the setting and collecting wagon in transverse section.

The present invention relates to apparatus adapted for the spinning of artificial'silk.

But a single spinning unit. is illustrated, it

being understood that in usual installations a series of such units is supported upon the frame 1 of the machine, and discharge a cellulose solution, such as viscose, intothe' setting bath 2 contained in a trough 3 extending the length of the frame. As here shown, the main frame is provided with a,

series of brackets, of which one, 1, is illustrated, provided at its outer end with aseat 5, upon which rests the/supply pipe 6 running longitudinally of the frame, and through which the solution is su plied to the several spinning mechanisms. etween the legs of the standard 7 above the supply pipe is pivoted the casing 8 of a rotary feed pump, driven by'the worm wheel 9 adapted to mesh with a worm on the longitudinal shaft 10v extending the length of the machine; Pivoted on the same axis between the standards 7, but independently of the pump, with which however it communicates, is the pipe 10 leading to and supporting the filter 11, from which emerges the stem 12 of the spinning nozzle-13, Upon the pipe 10 'is fixed a stop 14 which works between a pair of lugs 15, 15 on the pump casing 8.

Above the'pump and protecting it and the driving gear is an inclined drip shield 16 slotted at- 17 to permit the pipe 10 to work therein. The inneredge of the shield is down-turned at 17 to form a drip edge, from whichwaste solution falls clear of the pump and its mechanism to the drip pan 18 ivoted at 19 on the bracket, and provlded with a handle 20 by which it'may be swung to discharge position, shown in dotted lines.

In this position it empties its contents to a wagon 21 traveling along the floor of the work room, and having at one side a grooved wheel 22 running onthe guide rail 23 supported in the angle 24,0f the ,foot piece 25 of the frame.

' In the operation of apparatus of this type it frequently happens that the operative may desire to inspect the nozzle 13 to' observe whether or not its orifice or orifices have become obstructed. This operation can best be performed while the pump 8is still in operation.- In the present arrangement this is accomplished by grasping the upper portion of the filter 11 and tilting the latter from its spinning position, shown in full lines, to a raisedposition intermediate that shown in full lines and that indicated in dotted lines.- In this position the stop 14 on the pipe 10 moves away from the lug. 15 on the pump casing 8, but does not impinge against the lug 15. Inasmuch as the engagement between the worm wheel 9 and the worm on the shaft 10 is not broken, the pump con-' tinues to operate, and the feed to the nozzle is uninterrupted. The solution discharged from the nozzle is now deposited in the pan 18 and is" gathered for recuperation. Should casing and tilts-the latter on its axis to the position shown in dotted lines, thus lifting the worm wheel 9 out of mesh with the worm on the shaft 10 and automatically halting the feed from the pump by the interruption of the drive. The drip from the nozzle is now caught on the drip shield 13 and falls from the edge 17 to the drip pan 18, thus pi otecting the gear 9 and the associated elements beneath the shield 16' from fouling.

from what I claim as my invention.

. nozzle for rendering-the pump drive inop liquid thereto,

When the drip pans 18 on the frame accumulate suificient waste, the attendant passes in front of the frame with the wagon 21, and tilting the several pans 18, discharges their contents into the wagon.

. It will be observed that but a single motion by the operative is required to stop the feed to the spinning nozzle, and the motion is but a continuation of that-required to lift the spinning nozzle from the. setting bath. The lost-motion connection between the nozzle element and the pump casing neverthelessaifords opportunit "for the operative to inspect the nozzle ori ces without interrupting the flow of solution through the nozzle. The" return of the nozzle to the setting bath automatically restores the feed by reason of the impingement of the stop 14 against the lug 15 on the pump casing, so that the latter is automatically tilted againtoa position in which the worm wheel 9; V meshes with the worm on the spindle 10,

thus restoring the pump drive and the feed to the nozzle. I p

Obviously the filter 11 may bev arranged in any suitable position, and need not form a portion of the nozzle element, although I prefer this construction. Various modifications in detail of arrangement ofthe structural parts will readily occur to those dealwith the problem, without departing I claim- 1. In apparatus of the type described, a

movable spmnin nozzle, a pum delivering isconnectible riving gear forithe pump, and an operativeconnection between the nozzle and pump driving gear to disconnect the latter on the operative movement of the spinning nozzle in one direction. Y

2. In apparatus of the type described, a

spinning nozzle, a pump delivering liquid thereto, disconnectible driving gear. for the pump, and a lost-motion connection between the nozzle and gear for.-disconnecting the latter after a predetermined extent of movement of the spinning nozzle in one direction. l
